Silver Bullet

If you want to walk into a store look up places that supply/cater to machinist.
I have several Grainger stores around me. if they don't have it there, they just get it from another one their stores.
Other than that i usually order online.

McMaster-Carr, Grainger.com,Amazonsupply.com
 
I was looking to order online for changing the cant angle. But, McMaster-Carr is right up the street from me. I could go there, just to personally inspect the candy store and make sure everything is in order...
 
A pin Gauge Set is Great to have, especially for testing different Cants, testing Wheel bores and drilling your front at an angle! I use the sh1t out of mine since I got it!! About 50 bucks, maybe cheaper out there!

You were about 90 minutes late with that post Ice. I just bought enough blanks to drill 1.5 degree to 6 degree cants in 1/2 degrree implements.
